Personally, I find that there is a severe lack of good ranged options for many classes. On my Ranger, I feel the need to run Greatsword. On my Mesmer, I feel the need to run dual sword. On my Elementalist, I feel the need to run sword/dagger. I could respect melee having slightly higher damage, due to increased risks; however, I find the difference between a ranged build and melee build too large. Even if they were good, there is still usually more melee than ranged options available per class.
